java.lang.NullPointerException on MapFragment [duplicate] - java

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 5 years ago.
I'm trying to make a marker on Maps with data lat and long from web service, but it returns error null pointer. I do make log data and the lat and long data are retrieved on log successfully. Please help. Thank you in advance.
This is my KDetail.java
private PData data;
private static final String TAG = "KDActivity";
private Call<APIBaseResponse> call;
private RestClient.GitApiInterface service;
private Toolbar toolbar;
private SessionManager sessions;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_k_d);
toolbar = (Toolbar) findViewById(R.id.toolbar);
this.setSupportActionBar(toolbar);
sessions = new SessionManager(this);
Intent i = getIntent();
data = (PData) i.getSerializableExtra("PDItem");
txtIdP = (TextView) findViewById(R.id.txtIdP);
txtCdt = (EditText) findViewById(R.id.txtCreatedDtm);
txtIdP.setText(data.getId_P());
txtCdt.setText(data.getCreatedDtm());
final MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(new OnMapReadyCallback() {
#Override
public void onMapReady(GoogleMap googleMap) {
Log.d(TAG, "onMapReady: ");
double lata = Double.parseDouble(data.getLatP());
double lana = Double.parseDouble(data.getLangP());
googleMap.addMarker(new MarkerOptions()
.position(new LatLng(lata, lana))
.title("Start") );
}
});
}
This is the error :
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void com.google.android.gms.maps.MapFragment.getMapAsync(com.google.android.gms.maps.OnMapReadyCallback)' on a null object reference

Check is may be getSupportFragmentManager() or check the id is it map for sure?? Try it instead of getFragmentManager

OK here the problem at your XML file you using the support version of the map fragment and the code you search for the normal one. so to fix it you have two solutions
choose one from the two
1- change the name of the fragment at xml to
android:name="com.google.android.gms.maps.MapFragment"
2- change the MapFragment to SupportMapFragment at your java code

My JAVA codes:
public class UpdateActivity extends BaseActivity {
#BindView(R.id.dialogEndCount_buttonsLay)
LinearLayout dialogEndCount_buttonsLay;
private Window window;
private Activity activity;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_update);
//Initialize
ButterKnife.bind(this);
activity = this;
window = activity.getWindow();
//Set color to statusBar
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.setStatusBarColor(getResources().getColor(R.color.tabHomeColor));
}
//Set dynamically weight
dialogEndCount_buttonsLay.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
}
}
How can I fix this problem?

If you want set dynamically weightSum just use this code :
dialogEndCount_buttonsLay.setWeightSum(3f);
i hope help you

You're mixing LinearLayout and RelativeLayout. Change your layout to use a LinearLayout then weight is an available property on your LayoutParams.
val params = LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT)
params.weight = 1f

Android fragment oncreateview is called but view is not inflated and there are no errors

So I've done this a fair amount of times but I'm truly stumped this time. My fragment is called from my activity with no problems and although the onCreateView() is called, nothing at all shows up, still no errors. I've spent a couple hours looking for similar questions here with no luck.
Here is my swapFragment() method that calls my fragment:
private void swapFragment() {
GenresFragment genresFragment = new GenresFragment();
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.flgenre, genresFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
Here is my GenresFragment.java:
public class GenresFragment extends Fragment {
// TODO: Customize parameter argument names
private static final String ARG_COLUMN_COUNT = "column-count";
// TODO: Customize parameters
private int mColumnCount = 1;
private OnListFragmentInteractionListener mListener;
private DatabaseReference mPostReference;
String userID = FirebaseAuth.getInstance().getCurrentUser().getUid();
private ArrayList<String> genreList = new ArrayList<>();
private MyGenreRecyclerViewAdapter myGenreRecyclerViewAdapter;
/**
* Mandatory empty constructor for the fragment manager to instantiate the
* fragment (e.g. upon screen orientation changes).
*/
public GenresFragment() {
}
// TODO: Customize parameter initialization
#SuppressWarnings("unused")
public static GenresFragment newInstance(int columnCount) {
GenresFragment fragment = new GenresFragment();
Bundle args = new Bundle();
args.putInt(ARG_COLUMN_COUNT, columnCount);
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
mColumnCount = getArguments().getInt(ARG_COLUMN_COUNT);
}
}
#Override
public View onCreateView(LayoutInflater inflater, final ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_mini_add, container, false);
if (rootView == null){
Log.e("TEST1", "Is Null");
}else {
Log.e("TEST2", "Not Null");
}
return rootView;
}
public void failure(){
Toast.makeText(getActivity(),"Something Went Wrong",Toast.LENGTH_LONG).show();
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof OnListFragmentInteractionListener) {
mListener = (OnListFragmentInteractionListener) context;

I finally figured out the answer, all I had to do was change my root element(linear layout) to frame layout and it worked. Hope this helps someone. Thanks to everyone for their suggestions.

Try to modify you swapFragment() with below code by replacing replace() with add()
private void swapFragment() {
GenresFragment genresFragment = new GenresFragment();
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.add(R.id.flgenre, genresFragment);
fragmentTransaction.commit();
}

Other people already asked for the activity xml, but for what I could see right now, it looks like you are inflating the fragment's layout in a FrameLayout that is contained in it's own layout.
Meaning, the container you are inflating into should not be in the fragment's layout, but in the activity's layout.
Unless I understood it wrong, you should not have the with id/flgenre in fragment_mini_add.xml but in Activity_main.xml (or whatever the layout of the activity is)
Edit: in both activity and the fragment_mini_add.xml there is a layout with the same id you are trying to inflate into. I'm not sure if this causes the problem, but I imagine this could be the cause.

You should remove android:id="#+id/flgenre" in the first xml tag from your activity xml and fragment_mini_add.xml.
replace tools:context="com.nocrat.fanti.ProfileActivity" with tools:context="com.nocrat.fanti.GenresFragment" in fragment_mini_add.xml.
then, add this code to your activity xml to contain the fragment
<FrameLayout
android:id="#+id/flgenre"
android:layout_width="match_parent"
android:layout_height="match_parent" />

onClick listener cannot find one of my button fragments. Crashes when initializing button

So when I launch my app it just crashes because the button in my first fragment class cannot be found for some odd reason.
When I removed the
case R.id.button_accept : the program ran fine, so I was thinking it's most likely something I did with the XML in the register_user_fragment. So is there a specific way I need to call the button because there are multiple layouts in one class?
Here's the error.
Caused by: java.lang.IllegalStateException: Required view 'button_accept' with ID 2131296297 for field 'button_accept' was not found. If this view is optional add '#Nullable' (fields) or '#Optional' (methods) annotation.
Here's my baseactivity
public class BaseActivity extends AppCompatActivity implements View.OnClickListener {
//Fragments
Fragment usernameFragment;
Fragment passwordFragment;
//
FragmentManager fragmentManager;
#BindView(R.id.button_login)
Button button_login;
#BindView(R.id.button_accept) //CRASHES HERE.
Button button_accept;
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
//check if user is logged in or not
setContentView(R.layout.activity_login);
ButterKnife.bind(this);
usernameFragment = new UsernameFragment();
passwordFragment = new PasswordFragment();
fragmentManager = getFragmentManager();
button_login.setOnClickListener(this);
button_accept.setOnClickListener(this);
//setcontentview register page or whatever use is logged into
}
#Override
public void onClick(View view) {
switch (view.getId()){
case R.id.button_login :
Toast.makeText(this, "testds", Toast.LENGTH_SHORT).show();
fragmentManager.beginTransaction()
.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out)
.replace(R.id.content_login, usernameFragment)
.commit();
break;
case R.id.button_accept :
fragmentManager.beginTransaction()
.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out)
.replace(R.id.register_user_fragment, passwordFragment)
.commit();
break;
}
}

Because the "button_accept" is in your fragment layout , not in your activity layout :).
Your binding a UI component that doesn't exist on your activity layout.

You just made your layout mixed. just remove the Button accept_button from frame layout .
The problem is here you have button in a layout parent in which you are placing fragment dynamically. so remove the button to out side or to upper parent and out side the fragment container.

Saving several EditText after program closes

I'm trying to make a Character sheet for a DnD like game. The point is to take user input and store it for future viewing and changing. Maybe I'm looking for a solution that doesn't exists but I want the EditTexts to stay the way they are if the user closes the app or just goes back to the title screen. Following is part of the xml file for the user input, the java file is basically blank

Java file
package com.example.mapuchii.gurps;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class Character_activity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_character_redo);
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// Read values from the "savedInstanceState"-object and put them in your textview
}
#Override
protected void onSaveInstanceState(Bundle outState) {
// Save the values you need from your textview into "outState"-object
super.onSaveInstanceState(outState);
}
}

Here is one example:
public class Character_activity extends AppCompatActivity {
private EditText playerEditText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_character_redo);
playerEditText = (EditText) findViewById(R.id.player);
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
playerEditText.setText(savedInstanceState.getString("SavedPlayer", "");
}
#Override
protected void onSaveInstanceState(Bundle outState) {
outState.putString("SavedPlayer", playerEditText.getText().toString());
super.onSaveInstanceState(outState);
}
}
This will save your text over an orientation change. If you want to save it when your process is killed then you need to look at SharedPreferences instead of a Bundle.
